Can two streamlines in a fluid be tangential to each other not crossing each other?

A streamline cannot cross other one in steady state of a fluid but can they be tangent to each other ?

What I mean is consider fluid in steady state. if let us say particle A has its own path in fluid and at point B it has velocity x. But let us say another particle C has its own path and has to cross ppoint B it must also have same velocity and hence the two streamlines are tangent at B. Is this possible otlr is it only valid if particle A and C both have the exact same trajectory fro the beginning ?
